...that is not possible to dive a 767 at that speed of decent, that is 5500 feet per minute ...
As I mentioned earlier, our objective was to bring a line pilot’s perspective to the evaluation. So our first maneuver east of the mountains was a rapid descent, simulating loss of cabin pressure. To make this more interesting, and because it is standard procedure at some airlines, I flew the maneuver completely on the autopilot. I dialed the altitude from FL290 down to 11,000 feet, disconnected autothrust and brought the throttles to idle, dialed the speed up to 350 knots, and deployed the speedbrakes

sound tavels at 1100 fps.
an airplane travelling 500 mph is going @750 fps.
you would hear the plane before you see it.
the sound wave is travelling faster than the plane.
Sorry to say that aircraft were used.

It looked like a planned accident to me.

On the initial pitchover, the rate of descent increased to 9,600 feet per minute at 7½ degrees nose down, then slowed to 5,300 feet per minute as the airspeed stabilized at 353 knots. The time from start of the descent to level-off at 11,000 feet was just 3 minutes. Very impressive, particularly since we flew the maneuver by interfacing with automation, rather than manually.
It is, but the one posted earlier covers the same distance, though the time is somehow compressed in that other one, making it seem shorter.
